[LLVMdev] LazyValueInfo.getPredicateAt
Hi,
Is it intentional that LazyValueInfo.getPredicateAt doesn't solve for
the value and only takes assumptions into account?
getPredicateAt gets lattice value from cache using getValueAt call:
LVILatticeVal LazyValueInfoCache::getValueAt(Value *V, Instruction *CxtI) {
...
LVILatticeVal Result;
mergeAssumeBlockValueConstantRange(V, Result, CxtI);
...
return Result;
}
